[QUOTE="Thedual1, post: 2028344, member: 16806"] The high calcium lime will antagonise both phosphate and boron, so best backed up with foliar. I did quite a few trials last year on spring barley, winter barley and winter wheat with both foliar molybdenum and boron. In spring barley there was a definite reduction in blind grain sites. Soil Copper and zinc levels were very good as the site is on a piggery that gets lots of FYM and slurry. Kieserite is a good product also supplies sulphur, so once again watch antagonism with copper. I have started using mag lime to fix magnesium and calcium imbalances, been a struggle getting a decent product that I can guarantee how much calcium and magnesium it contains. If I put on too much magnesium I end up antagonising magnesium, therefore it is essential a full base saturation based soil survey is undertaken, before any recommendations of applications are made.
